Huge thanks to MorphiousGX for our live report form. Please report battery usages at these links.
We will use this information to help make better adjustments to our tweaks. It will collect the necessary information to make sure people compare apples to apples*

You can also view results after you submit, and filter on any of the questions asked (i.e. Tweaker's name, governor, release date..etc).

Splash Screens will only work on TouchWiz
Working on finding out the cause of these issues. Please report bugs in either of the Team Kernelizers threads.
This is still in Beta, more is yet to come!!!!!!

Kernel Information

General Installation Instructions (for both TW and AOSP):

1. Download correct version of kernel for your device and rom. This is important as you may brick your phone is you use the wrong version.
2. Flash kernel using your preferred recovery
3. Do the following AFTER installing the kernel and BEFORE you reboot your phone:
a. Clear cache
b. Clear dalvik
c. Fix Permissions
4. Reboot your device.

TW Specific Kernel Instructions:
(can be used with AOSP too)

There are some files on your TouchWiz phone that need to be renamed in order to maximize the battery life of your phone. There has been some debate on whether or not this is necessary, but for now we would recommend renaming these files to ensure that there is no chance of excessive battery drain.
Part 1:
These steps are only necessary on TouchWiz ROMs, however you can also do this on AOSP as well:
1. You must have ROOT. You will need to have a root enabled file explorer on your phone (ES File Explorer works very well and you can get it from the play store (https://play.google.com/store/apps/d...roid.pop&hl=en). When you get it, open it up and go the the settings and scroll all the way down until you see the Root Settings. Go in there and enable ALL of the root settings.
2. After that is done, navigate to your root folders using the Folder Up icon at the top. Once you are in your root folders, navigate to /system/bin and locate the following files. You will need to rename them with a ".bak" at the end of the filename
gsiff_daemon --> gsiff_daemon.bak
mpdecision --> mpdecison.bak
qosmgr --> qosmgr.bak
smd --> smd.bak
smdexe --> smdexe.bak
Renaming these files will not harm your phone. Many users rename these files every time they flash a rom, and no damge is done.
Also, some ROMs come with these files renamed or deleted entirely, so if you don’t find a file, don’t be alarmed.
You have to do this every time you flash the ROM and/or Kernel.
If you feel uncomfortable doing this yourself, you can use the TK-MOD (see Downloads section) and it will handle this for you.

Part 2:
Stopping mpdecision from being called:
1. Open terminal emulator and type the following code:
su
2. When terminal emulator asks for root permission hit 'Grant' or 'Allow'.
3. At the # prompt type:
stop mpdecision
Using Rom Toolbox (https://play.google.com/store/apps/d...iberty.toolbox) we will make a script that will stop mpdecision from being called at each boot so you don't need to use terminal emulator each time
1. Open Rom Toolbox and scroll down to the Scripter option
2. In the scripter, click the “+” button in the top right corner, then select 'Create'
3. Type a name for our new script, lets call it “stop mpdecision”
4. In the commands enter the following text:
#!/system/bin/sh
stop mpdecision
5. Hit the disk icon to save it
6. Select the script that you just created and a dialog box should pop up, select set at boot
Were done here

AOSP Specific Kernel Instructions:

When coming from a 3.0 Kernel to a 3.4 Kernel there is a new method with kernel updates. Skipping these steps will cause phone instability, due to some bad data left behind. This is a flaw in the Android OS, not the application. You must follow the instructions below (Thanks ktoonzs for the new method of the ktweaker app)
1. Go to Settings on the phone
2. Go to app manager then all apps
3. Scroll down to ktweaker app n open it
4. Once open hit FORCE STOP and then hit CLEAR DATA
5. Reboot and flash your new update of ktoonzs kernel
6. Repeat steps 1-4 in the above “General Installation” section
You should be good to go after that

@Maybelle
I've been following along and will be so bold as to put in my two cents worth. I am a general/vascular surgeon. I got into Android because I was pissed off about a tablet I had that Toshiba wouldn't update. That lead me to y'all in time. I cannot say enough about how much respect I have for the Android and XDA development community. You truely "stick it to the man" while making the platform better.

I have been following the events related to Exit_Only and can say that while I have a hard time understanding the details of what is evolving I do understand that he, as well as all of you on the TK team, have helped me and my ability to communicate with my patients and my colleagues using a phone that does a lot more than its manufacturers or carrier would have it do.

We have "kanging" in medicine too. As a matter of fact it is written into the Hippocratic Oath IMO. What we do not tolerate in medicine is claiming credit for another doctor's work, although we are free to use it to benefit our patients as long as we do not claim glory for ourselves.

Kudos to EO for defending his hard work and kudos to all the rest of y'all for rising to his defense. I would be proud to support a TK website if that is the direction you wish to go in. I only wish I was more knowledgeable and could contribute in a more technical way. With your help I will get there.

*Users with Ktweaker settings reseting: Freezing system tuner and or rom toolbox is a possible fix for either min/max mhz, scheduler or governor resetting in Ktweaker. Another way could be making a backup of your settings, clear data on ktweaker, reboot and restore settings twice as not all apply right first time and reboot again with restore settings immediately at boot.

*Ktweaker Issues if on Kt747 Kernel: could have issues on roms like Freegs3 and it is noted that if you prefer to use Ktweaker to set your settings vs script than make sure no conflicting script is running for example check /system/etc/initd/ for 70tweaks and remove or place somewhere for safe keeping to prevent conflicts with Ktweaker for example min max changing or voltage tables, governor or scheduler. This script in the example is Freezas script to set phone based on screen on and off and current battery level for example of some of its functions, there is nothing wrong with using scripts nor is there a problem with this script in particular. Just be aware there will be conflicts if used in conjunction with Ktweaker and or setcpu and the like.

-#*note#* (you can get away with one of these high threshold tunings and not feel laggy by using touch booster set to 384mhz on booster one and for touch two 486mhz which should help response time on any interactive action where in you touch the screen and immediately resume the normal minimum mhz as during touch boost the cpu still ramps based on load over the touch boost values if and as needed. It provides less frequency steps to target frequency during interactive use)*! 384/486 being conservative and 702mhz touch boost 1 756mhz touch boost 2 for more response and still will not be over target frequency during interactive use.

Battery Saving:
-Noop: best battery savings for all mobile but not the best data rates. Considered a simple i/o
-SIO: similar to noop but uses a little more battery with benefit of some deadlines.
-Zen: Combo of noop, sio and deadline.

-enable Hwoverlay and force gpu rendering (leave out Hwoverlay on touchwiz to prevent a noted video playback issue)
-Disable animations and transitions on launcher (or set to as fast as possible)
-Use Launcher options to force launcher into memory like in Nova Launcher (Thanks Pberge)

Create localprop and force app in memory thanks nonato

- Go to terminal type su hit enter
-Type all of the following and hit enter to add an app to local.prop and force it in memory. Nova Launcher would be as follows. If local.prop doesn't exist the command will create it.

echo sys.keep_app_1=com.teslacoilsw.launcher-1 >> /data/local.prop

-(Thanks nonato for posting this trick in Seeder thread.)

Fix Gtalk fully disable if it was removed and causing a wakelock (needs credit need to find poster of this)

Cyanogenmod Based tweaks

-enable memory management options
-disable dithering (dithering on smooths color transitions off can show a banding effect) (if not on a CM based rom the use dithering 0 build prop has same effect)
-16bit transparency (close to half the bandwidth needed for 24/32bit color)

Rename these files on Touchwiz as pictured in System/Bin to prevent unnecessary battery drain (thanks for pic Jcdominguez)

- Navigate like in this pic to system/etc
- Open initpostboot.sh
- Go to line 223 (i use droidedit free at play store to edit the file it makes it easy to find line numbers)
- Place cursor in front of mpdecision and insert a #. Save the file and exit and reboot. Thats all thats necessary to prevent stopping mpdecision from starting or showing errors over and over in logcat on Android AOSP 4.2.1.
-*Credit goes to Decimalman thank you

- Build prop i use and has been tested on 4.1.1/4.1.2/4.2.1
- Gtojim and I are running these without issues. Tested on freegs3, cm10.1, Paranoid android and PAKman (#*has not been tested with Morphology need feedback*#)
-credit for the build props goes to Rom Toolbox and an XDA member Custodian. Thank you Custodian. http://db.tt/q7S1s8yp
- Directions same as other build props we have listed. Until we have an easy install script this is for advanced users only who already have experience editing build.prop. I will always suggest using rom toolbox to do so vs manually editing your build prop file. Do not add all of them in without checking if the value exists already. You don't want double lines that one says the line and true and the other false, its hard to say but one may override the other. THIS IS NOT A BUILD PROP IT IS A SIMPLE TEXT FILE WITH ALL THE ONES I USE. THE BUILD PROP ENTRY IS TO THE LEFT OF THE EQUAL SIGN AND THE VALUE USED IS TO THE RIGHT OF THE EQUAL SIGN. YOU MUST SEARCH AND REPLACE OR ADD THEM MANUALLY.

Systctrl settings via Init.d (requires kernel with init.d support or enable initd with RyuInfernos apk link at bottom) (tested on same roms as Build Prop)

- * Thanks Zeppelinrox for talking some settings over with me.

- Help entropy pool
- read_wakeup_threshold to 1366
- write_wakeup_threshold to 128http://db.tt/NilQsqG6
- Init.d for systctrl with the above set already and other optimized values

- Here guys this one is without anything special for entropy the values related to it are set to default on this one
- read_wakeup_threshold 64
- write_wakeup_threshold 128
- randomize_va_space 2http://db.tt/rHcNuTfR

- Instructions:
Download. Using a file explorer, i like es file explorer go up from internal storage with a root explorer till you are at / you should see system, sys and much more. Go to /system/etc/initd/ and paste this file in there. Select it and go to properties of the file and select permissions. Change them to rwxrwxrwx. In other words enable read, write and execute for the three options user, system and other or whichever they are called. Now exit and reboot. Now at boot systctrl are applied. These are the presets system tuner sets plus a few tweaks by Freecharlesmanson (if you see him please be sure to give him thanks) and a fix for entropy where noted above.

I'M understanding that people are having problems getting it to work i will explain what you have to do there a few steps that you have to do to get it to work

STEP 1: Always make sure you use the wifi tether that is baked into your settings the one in your toggles want work

STEP 2: Open it up and for the those of ya'll that's using it for the first time it will take about 45 seconds before you can use it because its has to get all the permissions from SU so once that is done tap on the wifi sign and start broadcasting the tether

STEP 3: Now you need to hit your menu button on your phone and you will see access control tap on it and enable this will let whatever you wanting to connect to the wifi tether see that it is there

STEP 4: Now go to your laptop,gaming system and etc etc and click on android wifi tether that is your phone

STEP 5: Now go to back to your phone and open up the access control and you should see mac address and ssid there with box's to be check them these are the device trying to connect to your tether now that you have check the box's hit apply at the bottom of the screen and that gives your device access to the internet

1: What is TPR?
2: What exactly are the process you had us stop used for? Just curious.
3: Do I want to run a particular I/O scheduler? I am using your suggested current Ktoonz governor tweaks.

Thank you again,
Whiteice

TPR is another rom called The Peoples Rom

The 2 files that are renamed r stop because they cause bad battery drain with ktoonsnative gov and the mpdecision is stop because it keeps core 2 going even with the tweaks I have posted so you stop it to keep core 2 running on the tweaks saves battery more less

We have found that bfq is about the best one to use but you can use whatever one you want to you use bud
